Arizona @ Boston preview

Fenway Park

Last Meeting ( Jun 17, 2010 ) Arizona 5, Boston 8


After a spirited rally kept Boston in sole possession of first place in the American League East, the Red Sox look to ride that momentum on Friday in the opener of a three-game interleague series versus the Arizona Diamondbacks. Boston erupted for six runs in the ninth inning to complete a three-game sweep of Seattle. With their fifth win in six outings, the Red Sox shuffled one game ahead of idle Tampa Bay.

Boston has won five in a row against Arizona, which fell for the fourth time in five contests on Thursday after being handcuffed by Yu Darvish and Texas. The Diamondbacks dropped a 7-1 decision in the makeup contest to fall 3 1/2 games behind the National League West-leading Los Angeles Dodgers. Arizona would love to rebound with a repeat performance from right-hander Randall Delgado, who recorded his first career complete game in his last outing.

TV: 7:10 p.m. ET, FSN Arizona, NESN (Boston)

PITCHING MATCHUP: Diamondbacks RH Randall Delgado (3-3, 2.85 ERA) vs. Red Sox LH Jon Lester (10-6, 4.27)

Delgado recorded his second consecutive scoreless outing after scattering three hits in a 10-0 triumph over San Diego on July 26. The 23-year-old Panamanian was far from dominant in his lone appearance versus Boston, however. Then a member of the Atlanta Braves, Delgado took the loss after yielding four runs on six hits in 1 1/3 innings on June 23, 2012.

Lester posted his second victory in a row after allowing just four hits over seven scoreless innings and striking out eight against Baltimore on Sunday. The 29-year-old has been substantially better at home, posting a 4-0 mark and 2.95 ERA while limiting the opposition to just a .230 batting average. Lester won his lone career start versus Arizona, permitting two runs on four hits while striking out seven in 2010.

WALK-OFFS

1. Acquired at the trade deadline, veteran RHP Jake Peavy will make his Red Sox debut when he starts Saturday's game.

2. Arizona placed C Miguel Montero (lower back strain) on the 15-day disabled list Thursday. C Tuffy Gosewisch was recalled from Triple-A Reno and went 1-for-3 in his major-league debut.

3. Boston registered its majors-leading 11th walk-off win on Thursday. The franchise record is 13, which was set in 1940.

PREDICTION: Red Sox 7, Diamondbacks 5

About Units and “ROI”

Units are a standardized measurement used to determine the size of each of your bets relative to your bankroll. For example, if you have a bankroll of $200 and you bet 5% of your bankroll each time, each of your units is worth $10. A bettor with a $2000 bankroll who bets 5% per bet has units of $100. We use the number of units to standardize the amount the trend is up or down across different bet amounts.

ROI is the best indicator of success and measures how much you bet vs. how much you profited. Any positive ROI is good in sports betting with great long-term bettors sitting in the 5-7% range.
