If he could bottle it, he surely would. Anthony Alford flashed his remarkable potential on Friday night, going 3-for-3 with two doubles, a triple, two runs and an RBI for Triple-A Buffalo in an 8-3 loss to Lehigh Valley. The performance earned the former Petal High star a mention on the Prospect Report segment of MLB Network’s Quick Pitch. But that kind of performance has been rare for Alford this season. He is batting just .217 with a homer, 10 RBIs and eight steals in 42 games for the Toronto affiliate. During a brief stint in the big leagues, the powerfully built outfielder hit .143. Alford has been one of Toronto’s top-rated prospects for several years but, due in part to myriad injuries, has been fighting to find consistency. That search is the key to advancement for every minor leaguer, the key to moving off the prospect chart and into a big league job. Former Harrison Central star Bobby Bradley, a highly regarded Cleveland prospect, is scuffling in his second tour of Double-A ball. The lefty-hitting first baseman had a three-hit game for Akron on Thursday night that included his 12th homer. His power is not an issue; he now has 99 bombs in his five-year minor league career. Consistent contact is what he seeks; he is batting just .196. Former Mississippi State standout Brent Rooker, playing Double-A ball in just his second pro season, has been hot and cold for Minnesota’s Chattanooga club. He struggled much of the first two months, found a groove at the start of June, then fell into another funk. He has hit just .211 in his last 10 games — and is at .263 for the season — but did begin the second half on Thursday with a home run, No. 10 on the year. Sometimes, it’s just tough luck that stalls a prospect’s upward mobility. Ex-DeSoto Central star Austin Riley was playing well at Triple-A Gwinnett after his promotion from Mississippi, hitting .284 with four homers and 18 RBIs in 26 games for the Stripers. But Atlanta’s third baseman of the future suffered a knee injury that has kept him out since June 3. It’s unclear when he might get back on track.
