Axford Getting Tagged in Two-Strike Counts

Few relievers were as dominant as John Axford during his first two years as the Milwaukee Brewers' closer. Axford placed tenth among qualified 'pen arms in both park-and-league adjusted ERA (183 ERA+) and Wins Above Replacement (3.8) in 2010 and 2011, reaching the apex of his profession after enduring a career arc at times promising (he was a touted Notre Dame recruit) and depressing (he signed as a free agent with the Yankees 2006 after a stint with the Melville Millionaires, a Canadian summer league team that, ironically enough, doesn't pay players).

While he won't be suiting up in Saskatchewan again any time soon, Axford's last two seasons in the majors have been brutal. He has the fourth-worst adjusted ERA (88 ERA+) and ranks dead last in WAR (-1.6) among relievers since the start of the 2012 season, which helps explain how the St. Louis Cardinals were able to pick him up today for a player to be named.

The big difference between the version of Axford closing out games and finishing in the top 10 in Cy Young Award voting and the version mopping up blowouts is home run prevention. Axford surrendered a mere 0.3 home runs per nine innings in 2010-11, but 1.5 HR/9 in 2012-13. He's having a particularly hard time keeping the ball in the park in two-strike counts, when he seemingly should have hitters in his clutches.

Axford allowed just one home run in two-strike counts during the 2010-11 seasons, and he limited batters to a .169 slugging percentage -- more 100 points lower than the MLB average for relievers over that time frame (.260).

The last two years, though? Axford is getting touched up far more often when hitters have their backs against the wall.

Axford has coughed up the most two-strike home runs among relievers over the 2012-13 seasons (nine), and he's allowing a .318 slugging percentage.

Pitch selection may be part of the problem. He's throwing more two-strike fastballs in recent years (64% during the 2012-13 seasons) than he did as a shutdown closer (55% in 2010-11), an approach he might want to reconsider. Seven of the nine homers that Axford has given up in two-strike counts in 2012-13 have come off of the heat. Breaking out the breaking stuff more often could help Axford finish off hitters in St. Louis.


Understanding John Axford's Scoreless Streak

2013 has been a tale of two seasons for Milwaukee Brewers closer John Axford

Beginning the season with an Opening Day blown save, Axford's headaches continued in his next three outings (2.1 IP) when he yielded a total of eight earned runs on eight hits (including three home runs) and two walks with a fly-ball to ground-ball ratio of 13-to-1. After being demoted from his closer role, his next month's worth of appearances were primarily spent in innings other than the ninth, and he performed well, lowering his season peak ERA of 24.30 on April 9 down to 9.20 as of May 14.

And May 14 marks the last time Axford has let a run cross home plate

Since then: 

  • He's tossed 17.1 innings of scoreless baseball
  • Struck out 18, walking seven
  • Held hitters to a slash line of .180/.275/.213 with just 11 hits allowed. 

His turnaround has had a ripple effect on Milwaukee's bullpen, too, posting an ERA of 2.45 as a staff, which ranks second-best in baseball since that date.

Axford's success can be traced largely to his success against lefties

  • The most prominent deviation against left-handed opponents comes on the in-play rate; nearly a 14-point difference in the amount of pitches hit in play is enough to say that either a) Axford's approach has changed and his command has improved or b) it is simply a matter of coincidence.
  • When you are looking at the world through an analytic eye, you don't buy into "coincidences." So, despite the fact that Axford is throwing less pitches in the zone, evidenced by his 41.7% zone rate, lefties are swinging more frequently at pitches that are not in the zone (25.9% chase rate).
  • Consequently, lefites are having a more difficult time making hard contact on his offerings, as his signficantly decreased .155 WHAV indicates.

  • Early in the season, Axford was much too over the plate with his offerings aganst lefties, pitching into a portion of the zone where left-handed batters produce a large portion of their extra-base hits. 
  • While his command could certainly be better during his scoreless streak, he has made it a point to stray away from the lower portions of the strike zone with his offerings, focusing instead on the up-and-outside portion of the zone to which left-handers traditionally are less apt to generate extra-base hits.
  • Axford has also focussed more on 'painting' the edges of the zone more frequently than he did prior to his late success, especially down and inside. Since Axford is more cautious within the zone, lefties are finding difficulty in putting quality contact on the ball.

During Axford's scoreless streak

  • Early in the season, Axford pitched more frequently to left-hander's strengths within the zone resulting in solid contact and power
  • During his scoreless streak, lefties have primarily made contact on pitches that are in on their hands, and that has resulted in weaker contact and subsequent lazy fly-ball outs.

With the July 31 non-waiver trade deadline approaching, it's tough to say whether Axford's scoreless streak has made him a legitimate asset in a package deal. If it continues well in July, general manager Doug Melvin may have no other choice but to move him to a buyer in need of late-inning help out of the bullpen. But, for now at least, the Brewers may want to ride Axford's scoreless streak for as long as possible -- there hasn't been much worth cheering for this season.
