Yainer Diaz's season has been a struggle despite some promising underlying metrics. After an impressive .846 OPS in his rookie year and a solid .766 OPS last season, Diaz has only managed a .647 OPS so far this season. His offensive woes come despite showing an increased ability to elevate the ball and a career-high line-drive rate of 28.2% as of Tuesday. Meanwhile, he is producing an average exit velocity of 91.3 mph. Manager Joe Espada emphasized the need for patience, noting that Diaz's hard-hit balls just haven't translated into results yet.

Diaz's expected statistics give a more favorable outlook than his actual performance. With an expected slugging percentage of .499 based on the quality of his contact, his current .381 slugging suggests he is underperforming significantly. His batting average, expected to be around .280 based on his hard-hitting ability, stands at a disappointing .234. As he continues to bat cleanup, the Astros hope he can turn things around, especially in light of Yordan Alvarez's injury.

The Week 10 fantasy baseball waiver wire is brimming with potential boosts across key categories such as home runs, RBIs, stolen bases, and batting average. Willi Castro of the Minnesota Twins, rostered in 30% of leagues, is a multi-position player revitalizing his season after a sluggish start, posting a .283 average with three home runs and five RBIs in May. Toronto's Ernie Clement is making waves hitting .306 with comparable stats, while Isiah Kiner-Falefa, despite skepticism, offers solid run production as a versatile infielder.

For those seeking power, Agustin Ramirez of the Miami Marlins has emerged as a rookie catcher with seven home runs. Meanwhile, Addison Barger of the Blue Jays, hitting .292 with four homers, is a rising star to consider. Josh Bell’s current hot streak for the Nationals reflects a typical veteran resurgence, marking him as a player worth monitoring. For RBIs, Michael Busch is on fire, while Carlos Santana’s recent performance cannot be overlooked.

Riley Greene was the standout performer in a tightly contested game, hitting a homer and adding a crucial two-run double to help the Detroit Tigers secure a 5-4 victory over the Toronto Blue Jays. Alongside Greene, Zach McKinstry and Javier Baez also contributed with solo homers, leading the Tigers to their fourth straight win. The Blue Jays fought back with Bo Bichette's eighth-inning home run and Daulton Varsho's two-run shot in the sixth, but fell short as Detroit's Jack Flaherty notched six strikeouts in the win. The match showcased a thrilling back-and-forth, with Detroit's defense, particularly Baez's stellar play, being pivotal.

The New York Mets continued their dominance over the St. Louis Cardinals with a convincing 9-3 victory at Busch Stadium. The standout performer was Pete Alonso, who not only hit his eighth home run of the season but was also named the National League Player of the Month. Alonso's two-run homer in the fifth inning proved to be the turning point, lifting the Mets to a 4-3 lead. In addition to Alonso, key contributions came from Brandon Nimmo, who hit a leadoff homer in the seventh, and Francisco Alvarez, who recorded three RBIs. Starting pitcher Clay Holmes secured his fourth win of the season after allowing three runs over six innings.

On the Cardinals' side, they struggled to maintain their early lead, with starter Sonny Gray giving up six runs in just over four innings. Despite Masyn Winn's and Willson Contreras's contributions, the team could not capitalize on early chances as the Mets' offense proved too much. As the Mets prepare for another showdown with the Cardinals, they aim to extend their unbeaten streak against them.
