My thoughts: Mathews, high upside front end pitcher with a potential call up this year and at a low cost. Peralta, while not having his normal high K season he is still a solid pitcher with about equal K's as innings and at a lower price point than Gore. Hoerner is clearly an upgrade across the board to your middle fielders (average, runs, SBs) and at average cost. Burger, is a power bat at a relatively low cost. He does lack average and had a really bad start to the season, but is back on pace
