The San Francisco Giants placed right-hander Keaton Winn (elbow) on the 15-day injured list (retroactive to June 21) on Saturday with right-elbow inflammation. Winn will head to the shelf after allowing five earned runs on five hits (one homer) while walking one and striking out two in just 2 2/3 innings in a loss to the St. Louis Cardinals at Rickwood Field in Alabama on Thursday. It's the second time that the 26-year-old has been on the injured list already this year, and it leaves the Giants' starting rotation dangerously thin. It's unclear who will replace Winn in the rotation as we head closer to the All-Star break next month. Winn hasn't even been much of an option in NL-only leagues in 2024, as he's gone 3-8 with a bloated 7.16 ERA and 1.37 WHIP with 48 strikeouts and 20 walks in 55 1/3 innings over his 12 starts in his second year in the big leagues.

The San Francisco Giants placed outfielder Mike Yastrzemski (oblique) on the 10-day injured list (retroactive to June 21) on Saturday with a left-oblique strain and recalled infielder David Villar and outfielder Luis Matos from Triple-A Sacramento in corresponding moves. Yastrzemski was removed from Thursday's contest with his oblique injury and he didn't play on Friday before landing on the IL on Saturday. The 33-year-old left-handed-hitting outfielder will now likely miss more than the 10 days on the IL with his injury, and we may not see him again until after the All-Star break in mid-July. With Yaz now out, expect Austin Slater to pick up the most playing time in the outfield in the Bay Area. Yastrzemski is really only useful in deeper fantasy leagues against right-handed pitching. He hits the shelf with a .224/.304/.406 slash line with seven homers and 28 RBI in 192 at-bats this year.

New York Mets outfielder Harrison Bader and third baseman Mark Vientos are both out of the lineup on Saturday at Wrigley Field against the hosting Chicago Cubs. Brandon Nimmo is manning center field and batting second, with DJ Stewart drawing into the lineup in left field and batting fifth against Cubs right-hander Jameson Taillon. Veteran infielder Jose Iglesias is starting at third base and occupying the nine-hole in the lineup. Bader could use the rest after going hitless in nine at-bats with four strikeouts in his last three games to drop his season line to .262/.308/.374 with four homers, 27 RBI and nine stolen bases. Vientos is also struggling of late at the plate, going hitless in nine at-bats with three strikeouts in his last two games played.

Seattle Mariners second baseman Jorge Polanco (hamstring) went 2-for-4 with two home runs, three RBI, two run scored, a walk and a strikeout in his latest minor-league rehab game with Triple-A Tacoma on Friday night. Polanco was also able to play a full game on defense, so it would be a surprise if he's not reinstated from the injured list to join the team in Miami against the Marlins. The 30-year-old switch-hitter finally got his bat going during his rehab assignment, and fantasy managers in deeper leagues will be hoping he can carry that over to the big leagues. When he returns to the M's, he'll be carrying a weak .195/.293/.302 slash line with five homers and 14 RBI in his 159 at-bats. Despite his poor performance in Seattle so far, Polanco is going to see regular playing time at second base.

The Miami Marlins placed left-hander Jesus Luzardo (back) on the 15-day injured list on Saturday with a back injury. The Marlins were hoping Luzardo could start on Saturday against the visiting Seattle Mariners, but they have instead placed him on the IL once it was clear he was going to be unable to toe the rubber. Right-hander Shaun Anderson will make the spot start on Saturday instead. Luzardo was pulled from his last outing on June 16 against the Washington Nationals early after only 77 pitches after his back injury caused diminished velocity. With the All-Star break right around the corner in mid-July, it remains to be seen if Luzardo will return to Miami's rotation before that. A career-low 21.2% strikeout rate has led to an up-and down year for Luzardo, as he's currently 3-6 with a 5.00 ERA, 1.24 WHIP and 58:22 K:BB in 66 2/3 innings over 12 starts.
