Right-handed pitcher Ross Stripling announced his retirement from professional baseball on Monday with a post on X. Stripling will call it quits after failing to make the Opening Day roster with the Kansas City Royals this spring out of camp. The 35-year-old veteran was originally a fifth-round pick by the Los Angeles Dodgers in 2012 out of Texas A&M. He spent the first four years of his major-league career with the Dodgers and also made his lone All-Star appearance with the team back in 2018, when he went 8-6 with a 3.02 ERA, 1.19 WHIP and 136:22 K:BB in 122 innings pitched. Stripling really struggled on the mound in his final two years with the San Francisco Giants and Athletics, posting a combined 5.68 ERA and 1.44 WHIP in 174 1/3 frames. He ends his nine-year MLB career with a 4.17 ERA (4.06 FIP), 1.24 WHIP, 20.9% strikeout rate and 5.6% walk rate in 846 1/3 regular-season innings.

The San Francisco Giants recalled left-hander Kyle Harrison from Triple-A Sacramento on Monday, and the team's plan is for Harrison to work out of their bullpen, according to NBC Sports Bay Area's Alex Pavlovic. Harrison's velocity has improved in recent weeks and he had a 3.46 ERA and 1.31 WHIP with eight walks and 38 strikeouts in 26 innings over his six starts for Sacramento. The 23-year-old southpaw could eventually work his way back into the Giants' starting rotation, but for now he'll pitch in relief and won't really be much of a fantasy weapon. In his first two big-league seasons in 2023 and 2024, the former third-rounder went 8-8 with a 4.47 ERA (4.59 FIP) and 1.30 WHIP with 53 walks and 153 strikeouts in 159 innings over 31 starts for the Gigantes. It's encouraging that his velocity is back up, but fantasy managers will need to see more.

Toronto Blue Jays right-hander Jose Urena will make the start on Tuesday in Anaheim against the hosting Los Angeles Angels. The Blue Jays signed both Urena and right-hander Spencer Turnbull to big-league deals over the weekend, and Urena will be the first to get a shot in a starting role for Toronto this week. The 33-year-old veteran Dominican began the year with the New York Mets but was quickly cut after giving up five earned runs on seven hits (two homers) while walking one and striking out three in three relief innings against the Washington Nationals on April 28. He appeared in 33 games (nine starts) for the Texas Rangers in 2024 and was much better, posting a 3.80 ERA, 1.32 WHIP, 70:39 K:BB and one save in 109 innings. Urena will be a deep DFS sleeper, but the matchup is right against an Angels offense with a .650 OPS, which ranks 26th in baseball.

Colorado Rockies rookie right-hander Chase Dollander (finger) will start Tuesday night at Coors Field against the visiting Detroit Tigers. Dollander dealt with a split fingernail on his pitching hand in his last start on Wednesday against the Atlanta Braves, when he allowed just one earned run on two hits while walking three and striking out four in 5 2/3 innings for the second win of his career. The 23-year-old prospect has plenty of long-term upside, but he's been shaky so far in his first five MLB starts, posting a 6.48 ERA and 1.52 WHIP with 25 strikeouts and 10 walks in 25 innings pitched. Dollander will be a risky fantasy option on Tuesday night at hitter-friendly Coors Field coming off his finger issue while facing the first-place Tigers, an offense that currently ranks sixth in OPS among all big-league teams.

Cleveland Guardians right-handed reliever Paul Sewald (shoulder) suffered an isolated high-grade posterior deltoid strain in his right shoulder on April 28 and landed on the 10-day injured list on April 22 (retroactive to April 20). Sewald will be rechecked at two-week intervals to determine his progress and his readiness to start a return-to-throw program. The Guardians expect the 34-year-old veteran to be out for a while, and without a clear timetable for a return, it's safe to say that we probably won't see him back in the big-league bullpen until at least June. Sewald hadn't been good for the Guardians prior to his injury, either, as he had surrendered eight earned runs on 13 hits (three home runs) while walking two and striking out 15 in 11 2/3 innings over 14 relief appearances. Sewald does bring plenty of experience, though, with 85 career saves in nine MLB seasons.
