He's not going to keep it up. He always has had power but his average isn't going to be above .270 and he can't hit righties well. He can hit lefties and will hit 20-25 HRs if he gets 500 at-bats but I really doubt he gets that many.
This is not true. He is actually better against right handers vs lefties. TLR just likes to match-up left vs right and right vs left stuff. Not sure what his numbers are this year but know his numbers are better vs right than left careerwise. He will continue to get the PT if he keeps hitting the ball and giving the team a chance to win.
