Here are three things well be keeping an eye on around the baseball world throughout the day today: 1. Me sick to make MLB debut: The Guardians are bringing southpaw up to the majors for his today. The clubs second-rounder back in 2022 has climbed the minor league ladder fairly quickly to emerge at Triple-A this year, where hes posted a solid 3.47 ERA and 29.1% strikeout rate acro s 98 2/3 innings of work. Those are impre sive numbers for the 24-year-old, and now hell get the opportunity to see if his high strikeout rate can translate into the majors. The Guardians have managed to hang around the AL Wild Card picture despite soft selling this summer, but with in Toronto and in the midst of a tough season theyll need contributions from young arms like Me sick if theyre going to stay relevant down the stretch. 2. Harper, Castellanos race towards milestone: Phillies veterans and are both a considerable way into their respective careers at this point. While Harpers status as a two-time MVP far eclipses Castellanoss resume as a two-time All-Star, both have had impre sive careers where theyve generally served as above-average hitters acro s their combined 27 years in the major leagues. Now the C.J. Miles Jersey two teammates are chasing the same milestone: 400 career doubles. Theyll likely become the 199th and 200th players in MLB history to reach that benchmark in the coming weeks, as Harper currently sits at 397 career doubles while Castellanos sits just one behind him at 396 two-baggers for his career. The pair will look to tee off of Mariners right-hander (3.48 ERA) as the Phillies go for the sweep against Seattle this afternoon. 3. Royals pushing for Wild Card spot: Kansas City made the somewhat surprising decision to buy at the trade deadline despite being slightly below .500 at that point and on the periphery of the AL Wild Card race, but that decision is paying off to this point. An 11-6 record in the month of August has put them just 2.5 games back of the Red Sox and Mariners in the race for a playoff spot with a 65-61 record. Deadline additions have improved the club considerably, with , , and all injecting life into a previously weak offense while has settled in as a quality rotation arm with a 2.70 ERA in three starts for the club. Today theyll go for their second consecutive series sweep when they face the Rangers and an as-of-yet unannounced starting pitcher. Whoever starts for Texas will have to contend with rookie , who has a 2.47 ERA in 17 starts. Jerian Grant Jersey
