Altuve baserunning blunders can be longer than Harden defensive gaffes... if anything, why can't Bagwell advise on this perennial issue...? From... 2016: Altuve’s (non base-stealing) base-running since 2015 has cost the Astros more than half a win. In fact, the negative value Altuve’s accrued from his base-running woes has actually outweighed the value of all those steals — his total BsR since the start of last year is -4.0. I just had to reach out to Mitchel Lichtman, UBR proprietor, to ensure I wasn’t seeing things. Lichtman provided me a spreadsheet with the full outputs of the UBR calculations the last two years and assured me that, yes, this is indeed accurate. Jose Altuve really has been one of the five most detrimental base-runners in baseball since the start of last year, even moreso than David Ortiz. From last year: There is no improvement... a superstar, yes. But... my goodness, I would rather have Jose Abreu pinch run for him once he is exiled to the bench.
