Altoona concludes its four-game series against Harrisburg on Thursday, and no one is likely to be sorrier to see the Senators leave town than shortstop Alen Hanson. The Pirates' No. 5 prospect started the season hitting .204 in 13 games but has found his groove against the Nationals' Double-A affiliate.

Hanson, No. 65 on MLB.com's Top 100 Prospects list has broken out against Harrisburg with three straight multi-hit games and seven runs.

In the series finale, which can be seen on MiLB.TV at 6:30 p.m. ET, Hanson will have to face left-hander Matt Purke, the Nationals' No. 6 prospect, who will be trying to bounce back from his own disappointing start. Purke will be trying to prevent Altoona from sweeping the four-game set.

While Hanson looks to stay hot in Altoona, Aaron Judge, the Yankees' No. 9 prospect, will be trying to extend his successful start to the season for Class A Charleston. Judge has four straight multi-hit games and will attempt to stretch that streak as Charleston opens a four-game series at Delmarva. Judge, who was picked 32nd overall in the 2013 First-Year Player Draft, is 9-for-14 with four walks and seven runs in his past four games.

Leading the slate of pitchers in Minor League action Thursday is right-hander Kohl Stewart, the Twins' No. 4 prospect and No. 38 overall. Other pitchers ranked on MLB.com's Top 100 prospects list scheduled to start Thursday are right-handers Mike Foltynewicz (No. 52), Braden Shipley (No. 75) and Rafael Montero (No. 83). Fans can see Foltynewicz and Montero on MiLB.TV at 8:05 p.m. and 10:05 p.m., respectively.
