Toronto Blue Jays infield prospect Orelvis Martinez launched a 469-foot grand slam on Wednesday for Triple-A Buffalo. It was the only hit he had in the game, but it was a big one as it put the Bisons ahead in extra-innings and extended his hitting streak to 11 games. The 22-year-old is making his best case for a promotion, hitting .296 with six doubles, two home runs, 10 RBI, and 13 runs scored over 14 games in 2024. Bo Bichette has him blocked at shortstop though, so he'd have to play third or second base. Wherever he ends up, he'll bring plenty of pop with his 60-grade power.

Miami Marlins outfield prospect Victor Mesa Jr. had his second straight three-hit game and second straight game with a home run for Triple-A Jacksonville on Wednesday. After starting the season 4-for-22 (.181) with no home runs, the 22-year-old has gone 10-for-21 (.476) with three home runs over his last five games. Last season the lefty hit just .242 in 123 games at Double-A but he belted 18 home runs as a 21-year-old. In 2024, the Marlins' top-ranked offensive prospect is hitting .387 with three doubles, three home runs, nine RBI, and six runs scored. Per MLB.com, Mesa Jr. has an ETA of 2025, however, if the Marlins continue on their current path of futility it could make sense to get him some big league at-bats this season.

Toronto Blue Jays outfielder Daulton Varsho belted two home runs in Wednesday's game versus the division-rival New York Yankees, but it wasn't enough as his team fell 6-4. Varsho's first homer was a two-run shot that went 373 feet to right center field to score Davis Schneider in the second inning, and his second blast traveled 392 feet to give the Jays a temporary 3-1 lead during the seventh frame. The 27-year-old converted catcher had a strong spring training, and he's offering plenty of power with four round-trippers and eight RBI in 55 at-bats to begin the 2024 season. Even so, he's only batting .218 across 19 outings and will likely need to pick it up in the speed department (one stolen base) to overcome hitting in the lower part of Toronto's order. Varsho has a three-game series against the San Diego Padres starting on Friday, and in 21 games against San Diego since 2022, Varsho is batting just .147 with three bombs.

Oakland Athletics outfielder Esteury Ruiz went yard in his first start from the leadoff spot since March in Wednesday's 6-3 win over the St. Louis Cardinals, smashing a two-run jack in the third inning and also stealing a base. Ruiz's homer was a 412-foot two-run shot that brought Max Schuemann around to score. The A's surprisingly sent the American League's 2023 stolen base leader to the minor leagues following only three games to start the 2024 season, but Ruiz is swiftly demanding the attention of fantasy managers after tearing it up in the minors. The speedy 25-year-old center fielder is now batting .357 (5-for-14) with two taters, four RBI, five runs scored, and two swipes in just six outings in the major leagues. He'll look to stay hot during a three-game series against the Cleveland Guardians beginning on Friday. Across nine career games against Cleveland, Ruiz is hitting .333 (10-for-30) with five extra-base hits, six RBI, and four pilfers.

Oakland Athletics closer Mason Miller continued to solidify himself as the team's go-to ninth-inning option in Wednesday's 6-3 win over the visiting St. Louis Cardinals, picking up his fourth save of the season to protect the victory. Miller allowed a leadoff walk to Ivan Herrera but quickly settled in to retire the next three batters, striking out two. After giving up two runs in his first appearance of the 2024 campaign, the fire-balling 25-year-old right-hander has rattled off eight consecutive scoreless frames in the month of April and now owns a 2.00 ERA and 1.11 WHIP with 17 punchouts over nine innings overall (seven appearances). The A's aren't going to win very many games this season, but Miller's current pace suggests there is a pathway to the neighborhood of 25-30 saves if he maintains a grip on Oakland's closing job and doesn't get shifted back to the starting rotation.
