I’m calling these three pitchers the “70 percenters” because that’s approximately the odds I believe that they’ll each start the 2020 season in the Miami Marlins rotation.
Pablo López
As already stated, it was a tale of two seasons for López. Solid through the first half, then right off a cliff for the second. Luckily for him, the Miami Marlins likely believe that what they saw through the last month and a half of 2019 from López was an aberration.
Lopez led the starters in 2019 with a FIP of 4.28, which is suggestive that he was somewhat better than his 5.09 ERA would indicate. He should have another full season to prove it.
Jordan Yamamoto
Yamamoto was considered a “throw-in” by the Milwaukee Brewers in the trade that made Christian Yelich an ex-Miami Marlins center fielder.
Although Yamamoto walked a too few many, 4.1 per nine innings, his 1.144 WHIP would have registered as the best mark from amongst the starters if he had pitched a few more innings. Yamamoto only surrendered 54 hits in 78 2/3 innings for a .191/.292/.355 opposing slashline. His 15 starts yielded a 4-5 record and a 4.46 ERA overall.
Yamamoto made headlines by starting out his major league career by not surrendering a run until his third start. He had racked up a dozen strikeouts and allowed only five hits over his first 14 innings, and didn’t allow more than three hits in a game until his sixth start. In his final start of the season, he struck out 10 in six innings of one hit ball to defeat the New York Mets, 4-2.
Elieser Hernández
Elieser Hernández was leaps and bounds better in 2019 than in the season prior. He dropped his WHIP from 1.447 to 1.239 and increased his K-rate from 6.2 to 9.3.
In his second major league season since being selected in the rule 5 draft prior to the 2018 season, Hernández went 3-5 with a 5.03 ERA and struck out 85 in 82 1/3 innings, also trimming his walk rate from 3.7 down to 2.8. He’s currently got the inside track on a rotation spot, but he’s not set-in-stone either.
