Week Ahead: Kirby’s MLB Adventure

George Kirby

George Kirby

Frank Becerra Jr. / The Journal News / USA TODAY NETWORK

All eyes were on top prospect George Kirby when he was promoted by the Mariners in early May, and he threw six scoreless innings against the Rays in his first MLB start. He hasn’t paid dividends in the three starts since then, but there’s reason to believe patience will pay off.

Kirby has shown off his eye-popping stuff in the majors, including a fastball that’s averaged nearly 96 mph, along with a plus slider and changeup. However, Kirby’s exemplary control had just as much to do with his dominance in the minors as his plus stuff (2.34 ERA, 10.7 K/9, 1.6 BB/9 since 2019), and we are already seeing signs of that in Seattle with 20/2 K/BB in 20 innings.

He’s faced some challenges with his matchups thus far, including excellent lineups like the Mets and Boston, but the schedule changes for the better next week. Kirby has as favorable a two-start week as we could imagine, going on the road to face the Orioles and Rangers. Those two offenses rank 25th and 29th in OPS vs. right-handed pitching this season, and could allow for Kirby to finally gain some momentum after allowing a total of nine earned runs over his last two starts.

Hiccups come with the territory as young players are called up to the majors, and that’s often even the case with a prospect with as much polish as Kirby had prior to his promotion. Rather than be discouraged by his 4.50 ERA so far, fantasy managers have reason to be encouraged by the components that have led to a 3.39 FIP and 3.17 SIERA, as well as the imminent matchups.

-Tyler Wells’ control has been similarly excellent, with an elite 1.4 BB/9 through nine starts. Predictably, Wells has seen his velocity flounder after moving from a relief role last year, and the strikeout decline has followed with a 6.0 K/9 that is near the bottom of the league compared to 10.3 K/9 last season. The Orioles have also handled Wells with kid gloves, as he’s yet to throw 80 pitches in a game. Beyond the poor supporting cast, the pitch cap is a limiting factor in Wells’ ability to tally wins, but the elite control will certainly play for his WHIP. If you have reasonable expectations, Wells should be a solid addition and provides more reason for fantasy managers to move with a two-start week ahead.

-After missing April with a shoulder injury, it’s not a surprise to see Luis Castillo’s velocity down from its usually elite 97 mph for his fastball and sinker. Fortunately, we are seeing a promising trend recently with the velocity inching upward, averaging 96 mph over his last two outings. The cumulative strikeout and groundball rates are well down from his career norm, but the increase in velocity for what has traditionally been a slow starter gives reason for optimism as Castillo approaches a two-start week.

-Freddy Peralta’s shoulder injury is a tough blow for the Brewers, but it does finally give Aaron Ashby an opportunity as a regular member of the team’s starting rotation. Not surprisingly, Ashby’s control has been rough this season with a 5.3 BB/9 over 34 innings, but he’s still suppressed his ERA by missing bats and posting an elite 66% groundball rate. Ashby’s stuff continues to be electric, working primarily off a 96 mph sinking fastball and low-80’s slider. The poor control and resulting high pitch counts will limit Ashby’s innings naturally, but the stuff makes him the NL’s version of Framber Valdez and a must-add if he was dropped in your league.

The following pitchers are generally available in over 50 percent of fantasy leagues and have favorable match-ups this week:

American League

Tuesday, May 31: Konnor Pilkington vs. KC

Pilkington has been inconsistent so far, but the lefty has a good track record of missing bats in the minors, with a 10.7 K/9 and 3.04 ERA in 100.2 innings at Double-A last season. The lowly Royals lineup has a horrific .634 OPS against lefties this year.

Tuesday, May 31: Devin Smeltzer @ DET

Coming off the best start of his career, Smeltzer seems likely to get at least one more opportunity in the Twins rotation. The soft-tosser is set to face a weak Tigers lineup with a .663 OPS vs. left-handers.

Wednesday, June 1: Jeffrey Springs @ TEX

We’re getting to the point that Springs should be added in all leagues, but if still available, he has a great matchup ahead at Texas. The Rangers have struggled at the plate, including a .703 OPS against lefties.

National League

Wednesday, June 1: Mitch White vs. PIT

White hasn’t worked deep into games with the Dodgers yet this season, but he gets an opportunity next week against the Pirates. He’s fanned more than one batter per inning for his career and faces a Pirates lineup that ranks 22nd in OPS against right-handers.

Thursday, June 3: JT Brubaker vs. ARI

Despite poor control, Brubaker has started to come around in May with a 3.22 ERA and 26/9 K/BB in 22.1 innings. His schedule has helped, and it gets even easier facing a D’Backs lineup with a .639 OPS against right-handed pitching.

Saturday, June 4: Zach Davies @ PIT

Davies’ command continues to be mediocre as his ERA inches toward 5.00, but he remains a viable matchup play against Pittsburgh’s aforementioned weak lineup.
