No. 4 Martin Perez
Martin Perez has struggled in the 2023 season with the Texas Rangers, primarily due to his starting rotation spot changing multiple times, possibly leading to a 4.84 ERA. His potential was shown in 2022 when he achieved a 12-8 record with a 2.89 ERA. Subsequently, he entered free agency, but due to limited demand, he decided to accept the Rangers' Qualifying offer of $19,650,000.
While Perez has struggled with an increased hit rate and a rise in home runs, his control remains steady, maintaining a consistent walk rate. However, it's worth noting that his strikeout rate has declined from 7.7 last season to 5.6 this season. He's been hit more this year, with a hit rate of 10.1 compared to 8.2 last season.
At 32 years old, if you can secure him on a reasonable contract, Perez could potentially serve as a valuable option for 2-3 years. His experience and ability to pitch far into games could help a team wanting to make the postseason.
