During the spring, the young arms in the Marlins rotation gained popularity due to their strong results. Caleb Smith could be emerging as the ace of this evolving staff. Smith has won three of his first six starts with a 2.00 ERA, 3.00 xFIP and 0.83 WHIP. He’s also racked up 45 strikeouts in 36 innings against nine walks for a 26.9 strikeouts minus walks percentage. Smith’s limited hitters to a .168 batting average against which ranks fifth among all starting pitchers.
According to the Marlins, Smith’s first six starts rank highly in the the franchise’s history. Only Josh Johnson (2011) and Dontrelle Willis (2005) recorded a lower ERA through their first six starts. Smith also ranks second in batting average against and in WHIP. Entering his start versus the Cubs, Smith leads all qualified starters in WHIP while placing fourth in ERA and third in swinging strike percentage (34.9 percent).
Smith’s underlying data reinforces his surge at the onset of 2019. He’s increased his swinging strike percentage by 5.2 percent, upped his O-Swing (swings and misses outside the strike zone) by over seven percent and reduced contact by almost eight percentage points. Here’s a look at these categories along with his xFIP since the start of last year:
Through six starts last year, Smith owned a 4.40 ERA with 41 strikeouts against 15 walks while winning only one of his four decisions. With a depressed batting average against and Smith’s also lowered the average exit velocity of batted balls in play to 84.7 MPH, his breakout seems imminent. But, how’s he doing it?
For starters, Smith’s tweaked his pitch usage throwing fewer four-seam fastballs while deploying more change-ups. During a season when hard hit rates continue to rise across the fantasy landscape, Smith’s lowered his hard hit percentage to 26.3 percent this year compared to 33.7 percent yielded in 2018. As his data from Statcast suggests, the change in his approach helps keep hitters off balance:
Last season, Smith threw his four-seam almost 59 percent of his pitches compared to his change-up usage of 13.7 percent. Even with some regression, which will happen, Smith’s expected rates do not suggest a future collapse. Just normal migration to the mean. Plus, Smith’s change-up only generated a strikeout percentage of 14 percent in 2018 and whiff percentage slightly above eight. Check out his improvement with the pitch above.
By throwing more change-ups, it unlocks his four-seam. Smith’s also producing more ground balls this year with fewer line drives. Always a crowd pleaser. For an idea of his arsenal, check out his pitch plot maps over his last 36 innings:
Knowing regression will be inevitable, how Will Smith do the rest of the season? For an idea, here’s how his projected numbers from THE BAT and Steamer look with his season totals so far added in could look like at the end of 2019:
Smith’s THE BAT final projection: nine wins, 162 innings, 3.39 ERA, 1.13 WHIP, 191 strikeouts
Smith’s Steamer final projection: 10 wins, 159 innings, 3.34 ERA, 1.13 WHIP, 185 strikeouts
There’s no guarantee these numbers will occur, but, with both being so similar, it appears “K-leb” Smith in the midst of his breakout. Any speculative drafter would sign on for the above final line in the preseason from Smith. Heed the evolution within his arsenal along with his propensity to generate strikeouts when valuing Smith going forward. It appears he’s here to stay.

Player News
Daulton Varsho picked up three hits, three RBI and a homer in a win over the Angels on Thursday.
Varsho has only played in seven games this year, but they’ve been seven good ones. He’s homered three times already, and his slugging percentage is a remarkable — and entirely unsustainable — .727 over 22 at-bats. Varsho has been a mediocre offensive player in his two seasons with the Blue Jays, but it’s possible at the age of 28 he’s having a breakout campaign. Far from a guarantee, but possible.
Taylor Ward hit a two-run homer in a loss to the Blue Jays on Thursday.
Ward, 31, gave the Angels a 2-0 lead with a two-run homer off Chris Bassitt in the first inning. He’s now gone deep in two of his last three games, and it ‘improves’ his slash to .181/.224/.391. Ward has been one of the most hot/cold players players in the sport over the last few years, so fantasy managers who can afford to make some roster moves may want to look at Ward while the going is good.
Vladimir Guerrero Jr. picked up three hits and scored twice in an 8-5 win over the Angels on Thursday.
Guerrero also drew a walk. It gives the first baseman multiple hits in back-to-back games, and it’s the third time in May that he’s reached that mark. That’s helped raise his average from .268 to .295, and the only thing fantasy managers can be disappointed with is his .432 slugging percentage. That number should continue to climb as the season unfolds, but Vladdy Jr. has had some inconsistent seasons when it comes to power production.
Chad Green picked up his first save of 2025 with a scoreless ninth against the Angels on Thursday.
Green got the save after Jeff Hoffman worked in back-to-back games — and struggled — in the first two contests against the Angels. He struck out two and looked the part while needing just nine pitches to get through the inning. Hoffman should remain the closer, but Green is on his tail if the struggles were to continue.
Chris Bassitt allowed five runs — four earned — while working six-plus innings against the Angels on Thursday while picking up a win.
Bassitt allowed three runs over the first two innings on a pair of homers, but settled down over his next four frames. He came out to work the seventh, but ended up being charged for two more runs after leaving the contest. The 36-year-old veteran has forged a 3.35 ERA and outstanding 49/8 K/BB ratio over the first quarter of the season, but this wasn’t him at his best. He’ll get the Rays next week if the rotation order stays the same for Toronto.
José Soriano allowed three runs over five innings while not factoring in the decision Thursday against the Blue Jays.
Soriano left with a 4-3 lead, but it was erased quickly after his departure. The 26-year-old was not exactly dominant in his outing with eight hits allowed and four free passes, but he did strike out six to help balance things out a smidgen. Soriano takes an even ERA of 4.00 into a scheduled start against the Padres in San Diego on Tuesday. There should be better options for that one.
