01/15/2010 - Under Armour Pre-Season All-America - 2010 Kellen is a two-way player at 1B and in the OF with a tall and projectable frame. At 6'4, his foot speed is well above average as indicated by his 6.97 60. He utilizes his quick, athletic feet well in his defensive play, showing an aggressive approach in coming to get and playing through balls. Lateral movement is a plus as he takes proper routes/angles in tracking down balls. Glove action is soft, clean, and sure in making the plays. Throws show some carry and accuracy into his target through a loose arm action. Offensively, Marruffo shows loose hands that flash bat speed as he displays power to the pull side with the baseball jumping off his bat when centered. Swing path gets uphill at times, so he needs to square up his stance and work on hitting the top half of the baseball. Kellen has a lot of potential and will get plenty of looks from the collegiate coaches with his baseball abilities.
