If Padres hit a grand slam for record fifth straight game Friday, payout is $1200 on $100 wager

When teams hit a grand slam in a game, they obviously win nearly all the time. The San Diego Padres enter Friday night's series opener at Petco Park vs. the Houston Astros on a four-game winning streak largely because the Friars have hit a grand slam in each of those four games, an MLB record run. At William Hill sportsbook, that a grand slam is hit in Friday's game, which also includes the Astros, is a +1200 long shot on the moneyline odds. No is -2400.

This grand slam streak of four consecutive games, all coming against Texas, started Monday night with young superstar Fernando Tatis Jr. drawing national attention for breaking one of baseball's "unwritten" rules by homering on a 3-0 count with his team holding a big lead late in the game.

On Tuesday, it was Wil Myers doing the deed with a slam in the first inning for a 4-0 lead that the Padres would never relinquish in a 6-4 victory. Wednesday, Manny Machado hit a rare walk-off grand slam in the bottom of the 10th with the Padres trailing 3-2. It was Machado's 11th career grand slam and sixth walk-off homer. San Diego became the fifth team in MLB history to record a grand slam in three consecutive games, and first since the 2006 Chicago White Sox.

History was made on Thursday in an 8-7 10-inning win over the Rangers as Eric Hosmer hit a slam in the bottom of the fifth. Because grand slams are so rare, a moneyline price to see one hit in a game is generally around +1200 as it is for this game and the prop always includes both teams.

The record for grand slams in a season is 14 by the 2006 Indians and 2000 Athletics. By a player, it's 25 in a career by Alex Rodriguez. In a season, it's six by Travis Hafner (2006 Indians) and Don Mattingly (1987 Yankees).

Hitting two grand slams in a game has been done by a handful of players, but the only one do to it twice in one inning was the Fernando Tatis, the father of the Padres' star, in the third inning of an April 23, 1999, game vs. the St. Louis Cardinals. 

Houston's starting pitcher Friday is Lance McCullers Jr. and he hasn't allowed a slam in five starts this year. Neither has San Diego's Garrett Richards. Start time is 9:10 p.m. ET.
