Why is home field advantage no big advantage?

45 Comments

Buster Olney — or, rather, his research guy Kenton Wong — notes today that since the advent of divisional series play, the team with home field advantage in the divisional series has won
just 31 of the 60 series (25 of 48 since it changed to a 2-2-1 format in 1998). Since the advent of the LCS in 1969, teams with home-field advantage are 39-41.  So yeah, maybe home field advantage isn’t that huge of an advantage.

Which goes against our predispositions — as well as some pretty major home-road splits by some teams this season — which hold that home cookin’ does a baseball game good. I’m not sure anyone can come up with a great explanation for this, but here’s my stab:

The thing that gives you home field advantage is the better overall record. The thing that gives you the better overall record over the course of a long, long season is depth, both in the rotation and otherwise.  That depth, however, is seriously overrated in the postseason when you can do crazy things like lean on a couple of hot relievers and top starters, rather than go five deep, day-in-day-out. Meanwhile, the teams without home field probably had to fight tooth-and-nail to get their playoff spot, and thus were on more of a playoff footing longer, relying on a couple of top guys.

There might be a dozen things wrong with that, but I can’t do any better. Well, I could cite random chance, but people really, really hate when you do that when talking about baseball.

Blue Jays place Aaron Sanchez on 10-day disabled list

The Blue Jays placed right-hander Aaron Sanchez on the 10-day disabled list with a contusion in his right index finger, per a team announcement on Saturday. The assignment is retroactive to Friday. In a corresponding move, righty Marcus Stroman was activated from the DL (right shoulder fatigue) and will take the mound for the Blue Jays at 9:07 PM ET tonight.

Sanchez, 25, is in his fifth season with the club. He hasn’t looked his sharpest so far this year, going 3-5 in 15 starts with a career-worst 4.52 ERA, 5.1 BB/9 and 7.6 SO/9 through 79 2/3 innings. It’s not yet clear how long he’ll be sidelined, though he could miss as little as one turn in the rotation before returning to the roster in the next week or two.

Sanchez isn’t the only struggling starter in Toronto’s rotation, either. Per MLB.com’s Gregor Chisholm, the team placed southpaw Jaime Garcia on the DL (right shoulder tenderness) as well, with lefty reliever Tim Mayza scheduled to take his spot on the roster. In 13 starts this season, Garcia carried a 2-6 record, 6.16 ERA, 4.5 BB/9 and 8.2 SO/9 over 61 1/3 innings. Any further decisions pertaining to the rotation — including Tuesday’s starter against the Astros — have yet to be publicly addressed.
