Athletics right-hander Elvis Alvarado got off to a rough start to the 2026 season, posting an 8.38 ERA across 9 2/3 innings before being sent down to Triple-A in mid-April. However, the 27-year-old has been much better since being recalled by the A's in early June, allowing just one earned run while striking out 13 and recording two saves across 8 1/3 innings. Alvarado is averaging 99 miles per hour on his fastball and has struck out 30.6% of the batters he's faced so far this year. The Athletics have also struggled to fill their closer role, as left-hander Hogan Harris leads the team with six saves but also owns a 14.8% walk rate and a 1.54 WHIP. If Alvarado can continue his recent hot stretch, he could emerge as the preferred option in the ninth inning for the A's. Deeper-league fantasy managers in need of saves should consider targeting Alvarado on the waiver wire.

Across 277 plate appearances entering play on Sunday, San Francisco Giants outfielder Jung Hoo Lee had hit .331/.361/.462 with four home runs, 26 RBI, 39 runs scored, and four stolen bases. The 27-year-old is one of the hardest players in baseball to strike out (9.4% strikeout rate), which provides him with a solid batting average floor. Lee owns just a 2.5% barrel rate and a 30.4% hard-hit rate, so he's unlikely to provide fantasy managers with much power production. He's also not a significant speed threat, as his career high for stolen bases in a season is 10. Still, Lee is a consistent presence in the Giants' lineup who should provide fantasy managers with an excellent batting average and solid counting stats as long as he stays healthy. For rosters in need of batting average, Lee should be a priority waiver wire target.

Across 214 plate appearances this season entering play on Sunday, Detroit Tigers infielder Colt Keith had hit .261/.308/.382 with four home runs, 16 RBI, 27 runs scored, and three stolen bases. While Keith's season-long numbers do not jump off the page, he's slugged .553 and hit all four of his home runs across 41 plate appearances in June. Keith's 8.3% barrel rate and 42% hard-hit rate do not suggest high-end power upside, but his .429 xSLG still indicates that he's been unlucky in the power department in 2026. As the weather heats up in Detroit, Keith could bring some improved power production for fantasy managers. The 24-year-old may be worth targeting as a streaming option on the waiver wire in weeks where Detroit faces a run of right-handed pitching.

Texas Rangers starting pitcher Jack Leiter (ankle) has been placed on the 15-day injured list due to a posterior impingement in his right ankle. The 26-year-old has been pitching through ankle issues since late April. However, his performance has taken a turn for the worse in recent weeks, as he's allowed 15 earned runs across his last 13 2/3 innings pitched (three starts). Leiter's overall line for the year is unimpressive, as he's recorded a 3-7 record with a 5.29 ERA, 1.44 WHIP, and 83 strikeouts across 80 innings (15 starts). Still, working around discomfort in his ankle may be a contributing factor in Leiter's struggles. If he's able to make a full recovery, Leiter carries some strikeout upside for fantasy managers upon his return. Rangers right-hander Cal Quantrill could be the favorite to assume Leiter's role in the starting rotation while Leiter is sidelined.
