When comparing Edwin Diaz’s statistics from his time with the Seattle Mariners and the New York Mets, it’s clear that there are some significant differences in his performance. Diaz had a lower ERA, WHIP, higher strikeout rate, save rate, and home run rate with the Mariners, but struggles with command and control with the Mets. Factors like the team’s defense and the park played a role in this difference, but improvements in command and control can help him regain his elite closer status.

Differences in ERA and WHIP

Edwin Diaz is a relief pitcher who has had success at both the Seattle Mariners and the New York Mets. However, when we compare his ERA and WHIP during his time with the two teams, we see a significant difference. With the Mariners, Diaz had a 2.64 ERA and a 0.79 WHIP in his three seasons with the team. However, with the Mets, his numbers have been less impressive, with a 4.95 ERA and a 1.38 WHIP.

One possible explanation for the difference in performance could be attributed to the team’s defense. The Mariners have consistently been near the top of the league in defensive efficiency, while the Mets have ranked near the bottom. This could mean that Diaz is receiving better defensive support in Seattle, leading to fewer runs being scored against him.

Another factor to consider is the difference in parks. The Mariners play their home games at T-Mobile Park, which is a pitcher-friendly park with a large outfield. On the other hand, the Mets play at Citi Field, which has a smaller outfield and is known to be a more hitter-friendly park. This could also contribute to the increase in ERA and WHIP for Diaz with the Mets.

It’s worth noting that Diaz has also struggled with his command and control since joining the Mets, resulting in walking more batters and leaving more pitches up in the zone. This has also led to more home runs and a lower strikeout rate.

Overall, while the defensive support and park factors likely play a role, there are also several other factors that have contributed to the differences in Edwin Diaz’s ERA and WHIP between the Mariners and the Mets. With more improvement in his command, control, and pitch sequencing, it is possible to see better numbers from him in the future.

Comparison of Strikeout Rate

Team	Strikeout Rate
Seattle Mariners	15.2
New York Mets	13.3

Edwin Diaz is known for his ability to strike out opposing hitters, which is evident in his impressive strikeout rate. When we compare his strikeout rate with the Seattle Mariners to his strikeout rate with the New York Mets, we see a significant difference. In his three seasons with the Mariners, Diaz struck out an average of 15.2 batters per 9 innings, while with the Mets, that number has dropped to 13.3 batters per 9 innings.

One possible explanation for the decline in strikeout rate is a change in pitch selection and usage. With the Mariners, Diaz relied heavily on his fastball and slider, which are both known to be strikeout pitches. However, with the Mets, he has thrown his fastball less often and relied more heavily on his changeup and curveball, which are not as effective at generating strikeouts.

Another factor to consider is Diaz’s command and control. With the Mets, Diaz has struggled with his command, which has resulted in more walks and more pitches being left up in the zone. This has led to fewer strikes and more balls in play, which in turn can lead to fewer strikeouts.

It’s also notable that with the Mets, Diaz has been used in a different way than with the Mariners. He has been used in more high-leverage situations, leading to him facing a more selective and harder lineup resulting in higher rates of contact.

In conclusion, a decline in strikeout rate can be attributed to several factors, including a change in pitch selection, usage, command, control, and different role and usage. With further improvement on these elements, Diaz could regain his high strikeout rate and return to being one of the most feared closer in the league.

Comparison of Save Rate

Team	Save Rate	Save Opportunities
Seattle Mariners	89.3%	78
New York Mets	78.3%	50

Edwin Diaz is a relief pitcher known for his ability to close out games and convert save opportunities. When comparing his save rate with the Seattle Mariners to his save rate with the New York Mets, we can see a difference in performance. With the Mariners, Diaz had an exceptional save rate, converting 57 of his 62 save opportunities for a 92% success rate. However, with the Mets, his save rate is not as impressive, converting 24 of his 30 save opportunities for an 80% success rate.

One possible reason for the decline in the saving rate could be a change in role and usage. With the Mariners, Diaz was primarily used as the team’s closer and was given a significant number of save opportunities. With the Mets, however, his role has been less defined, and he’s been used in a variety of different high-leverage situations. This could mean that he has had fewer saving opportunities, leading to a lower saving rate.

Another factor to consider is Diaz’s performance in high-leverage situations. With the Mariners, Diaz had a strong track record of performing well in high-pressure situations, whereas, with the Mets, he’s struggled to replicate that success. It could be that he’s not as effective in these high-leverage situations, which would negatively impact his saving rate.

It’s also worth noting that with the Mets, Diaz has struggled with his command and control, which could have led to more walks and home runs, putting him in more difficult situations.

In conclusion, while a decline in saves rate could be attributed to several factors including a change in role and usage, performance in high-leverage situations, and command and control, Diaz has the ability and the track record to improve and return to his high save rate performance.

Comparison of Walk Rate

Team	Walk Rate
Seattle Mariners	2.1
New York Mets	4.2

Edwin Diaz is known for his ability to throw strikes and limit the number of walks he issues. However, when we compare his walk rate with the Seattle Mariners to his walk rate with the New York Mets, we see a significant difference. In his three seasons with the Mariners, Diaz had a walk rate of 2.6 walks per 9 innings, while with the Mets, that number has increased to 4.3 walks per 9 innings.

One possible explanation for the increase in walk rate is a change in command and control. With the Mariners, Diaz had good control over his pitches, consistently throwing strikes and limiting the number of walks he issued. However, with the Mets, he has struggled with his command, resulting in more walks and more pitches being left up in the zone. This could be due to the different approaches and strategies of the team or the different coaching staff.

Another factor to consider is Diaz’s pitch selection and usage. With the Mets, Diaz has relied more heavily on his changeup and curveball which are pitches that have a higher chance of being ball compared to his slider and fastball. This could have resulted in more balls being thrown, resulting in more walks.

It’s also notable that Diaz has been used in different roles and usage with the Mets, leading to him facing a more selective and harder lineup, resulting in more difficult at-bats and more walks issued.

Overall, while the difference in approach and strategy of the team and different roles and usage likely play a role, there are also several other factors that have contributed to the differences in Edwin Diaz’s walk rate between the Mariners and the Mets. With more improvement in his command and control, it is possible to see better numbers from him in the future.

Comparison of Home Run Rate

Team	Homerun Rate
Seattle Mariners	0.4
New York Mets	1.4

Edwin Diaz is a relief pitcher who has had success at both the Seattle Mariners and the New York Mets. However, when we compare his home run rate during his time with the two teams, we see a significant difference. With the Mariners, Diaz had 0.8 home runs per 9 innings, while with the Mets, that number has risen to 1.5 home runs per 9 innings.

One possible explanation for the difference in home run rate is the parks in which the teams play. The Mariners play their home games at T-Mobile Park, which is a pitcher-friendly park with a large outfield. On the other hand, the Mets play at Citi Field, which has a smaller outfield and is known to be a more hitter-friendly park. This could contribute to the increase in the home run rate for Diaz with the Mets.

Another factor to consider is Diaz’s command and control. With the Mets, Diaz has struggled with his command, which has resulted in more walks and more pitches being left up in the zone. This has led to more pitches being hit for home runs, thus increasing his home run rate. It’s also notable that with Mets, Diaz has been used in a different way than with the Mariners. He has been used in more high-leverage situations, leading to him facing a more selective and harder lineup resulting in higher rates of extra-base hits.

Overall, while the park factor likely plays a role, there are also several other factors that have contributed to the differences in Edwin Diaz’s home run rate between the Mariners and the Mets. With more improvement in his command, control, and pitch sequencing, it is possible to see a better performance in terms of home runs given up.

Conclusion

In conclusion, after comparing Edwin Diaz’s statistics from his time with the Seattle Mariners and the New York Mets, we can see that there are some significant differences in his performance. Specifically, we found that Diaz had a lower ERA and WHIP, a higher strikeout rate, save rate, and home run rate with the Mariners. However, with the Mets, Diaz has struggled with his command and control, which has led to more walks, home runs, and a lower strikeout rate.

One possible explanation for the difference in performance could be attributed to the team’s defense and the park. The Mariners have consistently been near the top of the league in defensive efficiency, while the Mets have ranked near the bottom. Additionally, the Mariners play their home games at T-Mobile Park, which is a pitcher-friendly park, while the Mets play at Citi Field, which has a smaller outfield and is known to be a more hitter-friendly park.

Considering all this, it is important for Diaz to continue to focus on his command and control in order to be more effective. With his high-powered arm, if he can improve on this aspect, he will become a dominant closer once again. It is worth noting that the Mets have been using him in different way and in more high leverage situations, which might have contributed to his struggles, but this can also make him a more valuable asset for the team in the future. Given the talent he has, it is only a matter of time before we see him perform at his best again.
