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.
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.
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 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.
