Lake's career 650 PA pace for his career is still 2.95 WAR (2.62 this season) but he hasn't actually helped the team nearly as much as that may imply http://i.imgur.com/BbxrQnI.png so despite being well above average in a context-neutral setting, he's been below average on a per-play basis (WPA); this is driven by a poor clutch score (How much better or worse a player does in high leverage situations than he would have done in a context neutral environment): 2nd-worst on the team during that time, trailing only Ryan Sweeney but he's still the best OF on the team (faint praise), so you'll want to keep playing him, but for whatever reason that you want to theorize he's clearly been hopelessly inept in run-producing situations, so i'd greatly prefer just batting him leadoff until he proves ineffective there, in which case we'll hopefully have an upgrade available by then also, he's struck out in 12 of 17 career pinch-hit ABs, which is kind of amazing
